Oprah Winfrey
Oprah is a famous American talk show host who has always publically struggled with her weight. She recently started the ‘slim fast’ diet that involves dramatically cutting back on the amount of food she eats replacing each meal with milk shake. Throughout a 6 week period Oprah struggled to resist eating snacks and food other than the milkshakes that weren’t allowed on the diet and often relapsed. After this time she weighed herself and became frustrated that her weight had actually increased compared with her friend Rachael who rather than using a restriction diet simply tried to eat healthy balanced meals.

Restraint Theory
Herman and Mack (1975) suggest attempting not to eat increases the probability of eating.

Boundaries model
This explains how dieting leads to overeating.Hunger usually keeps intake of food above a safe minimum.Satiety keeps intake below a safe maximum level. Herman and
Polivy (1984)AO1Slide9

SatietyDieterDiet boundaryDieter have a larger range between hunger and satiety because it takes longer to feel hungry and more food to satisfy them
Restrained eaters have a target or boundary they try to stick to but this doesn’t make them full so they keep eating!Slide10
Peter Kay
Peter Kay is a famous comedian who is currently very over weight and struggling to lose it! He has tried different diets including the Atkins diet, detox diet and weight watchers but has found none of them work very well. Peter finds that every time he tries to restrict his favourite foods like doner kebabs he ends up thinking about them all the time. This just gets worse and worse the longer he stays on a diet. After several weeks on his last attempt to lose weight peter ended up going out with some friends to the pub for a few drinks finally ending up the kebab house devouring a
doner. Slide11
Role of denial
Cognitive Psychology has shown if you try to suppress a thought on a regular basis you end up thinking about it more!Wegnar et al (1987) demonstrated this.Ask 1 group of PP’s not to think about a white bear and 1 group to think about itBoth groups instructed to ring a bell if they did. 1
st group rang the bell more.Theory of ironic processes of mental controlAO1Slide12
Adele
Adele is a super star who has a world renowned voice. Adele has always struggled with her weight and has tried many different diets. The most successful type of dieting Adele has tried involved focusing on the different foods that formed her 3 meals a day. Her nutritionist has given Adele a diet plan with many different recipes to stop her becoming bored with the same old routine. This has proven to be quite successful and Adele enjoys shopping and preparing different ingredients written down on the plan for each meal that she has. Slide13
Detail
Attention to WHAT we eat is the key to successful diet according to Redden (2008).Focusing on the detail of meals stops people becoming bored of the diet/eating experience.Gave 135 pp’s 22 jelly beans, one at a time. When each bean was given out information was flashed on a computer screen.G
roup 1 saw general info (Bean 6). Group 2 saw info on flavour. Group 1 got bored of eating quicker than group 2.AO1Slide14
